18650 Battery Storage Tray

A six-cell desktop tray for keeping loose 18650 cells separated instead of rolling around a drawer. The pockets use 18.8 mm nominal diameter plus clearance. Protected cells can be larger than bare cells, so measure yours. This is passive storage only and does not prevent shorts, charging faults, or fire. Includes STL and editable OpenSCAD source. Digital download only; no physical object is supplied.
